SHlNGLE-SAWING MACHENE.

SPECIFICATION forming part of Letters Patent No. 296,525, dated April 8, 1.884.

A pplication filed March 17, 1883. (No model) To aZZ whom it may concern,

Be it known that we, JOHN CHALLOXER and J OHN WM. CHALLONER, of Omro, in the county hereby declare that the following is a full, clear,

and exact description thereof.

Our invention relates to machines for the manufacture of shingles; and it consists in a machine which is adapted to saw shingles from the spalt as well as from the block, thus utilizing what has heretofore been a waste product, all as will be more fully set forth hereinafter.

In the drawings, Figure 1 is a front elevation, Fig. 2 is a side elevation, and Fig. 3 a top view, of our machine adjusted for sawing shingles from the block. Fig. i is a top view of the machine with the spalt-framc in place. Figs. 5 and 6 are details of the tipping-table supports, and Figs. 7 to 10 are views of the spalt-frame and its details.

A. is the main frame of the machine, and is made, preferably, of angle-iron. The front of this frame (shown in Fig. 1) extends inward at the center, as shown at A, to afford room for the swinging supports of the tipping table, while the fiat top of the angleiron of said frame forms a shelf or hearing, A, for the stationary supports of said table, the said support being shown in detail in Figs. 5 and 6.

B is leveling-bar, with central hub, 13, having a transverse perforation, b, and an end housing, B with perforation b for containing a spring, B There are also three front projecting lugs, 13* l3 B", each with a screw-threaded perforation and two rear lugs, B B one at each end, each provided with two screw-threaded holes.

G is a swinging frame of general T shape, the top of which is. cut away at the center at c, and this cut-away part admits the hub 13 of the leveling-bar, and then a bolt, 0, is passed through holes o c in the swinging frame and the hole I) in the hub, and the frame 0 is suspended from the bolt in the hub. This frame 0 has a front recess, 6, and a second recess, CF, back of this.

O is a securing-plate bolted to the lower part of the stem of the-T-frame G, and the leg or standard D of the tipping table rests in the recess 0, and is held in place by the plate G and its attachments, to be hereinafter de scribed.

The leveling-bar B is secured in place in the following manner: Adjusting-screws If I) at one end and b at the other end are passed down from the top of the bar through the holes in the lugs, the screws 1) and b resting on the shelf A of the main frame, while the screw b rests on a lug or extension, a of the said shelf. When the proper adjustments have been made and the bar 13 is level to they work of the machine, it is secured in that position by the binding-screws b N, one at each end, passing through the shelf A and the lugs 13 and B respectively.

The left wing of the T-frame O is bifurcated for the reception of a link, 0, the end of which is pivoted therein, while its other end is similarly pivoted between the forks of a bifurcated block, B", which slides in the housing 13 and is governed by the spring 13 already named, while tension of said spring is regulated by a block on the end of screw-boltl3,which passes through a hole in the plate B at the outer end of the said housing.

E is a handlever attached to one end of the Tframe O for tipping it, and F is a similar lever for automatically tipping the said frame and its attachments, as will be described further on.

plate O, and also carries a jam-nut, so that when the standard has been raised to the proper height it can be held rigidly in such position by means of the screw 0 and nut just named.

The main frame A rises to some height above the plane of the front central shelf, A

at each side, and upon the top of this frame an auxiliary frame, A, rests, and is securely bolted thereto. This latter frame serves as a Z, and which frame carries acontinuous knife-' supportfor the head-blocks G G, which sustain the guides of the carriage, the base of said blocks being provided with shoulders a for lateral adjustment, moving in correspondingly-shaped ways in bracket-extensions a of the auxiliary frame A. Midway between these brackets a, 011 each side of the auxiliary frame, are the slotted flanges a, to receive the bolts G, which extend down through the h ead-bloeks G, in order to secure the latter in place when they have been laterally adjusted in or out, as required.

To the inside of each head-block, at each end, are pivoted bell-cranks H H and H H, the latter being near the front of the machine, and having theirvertical arms extended up into the levers H the top of said levers being bifurcated, and having pivoted between their forks the tops of the depending pawls H which are kept in mesh by the springs W with the teeth on the segments I. The vertical arms of the bell-cranks are connected together by the links h, while their other arms are perforated for the reception of studs 7c on the guides'K. The segments I are provided with vertical slots, through which pass the bolts h, which also serve to secure the bell-cranks H to the head-block G, and a perforated flange, i, proj ects from each segment, through which depends an adjusting-screw, i", the point of which bears upon a collar, 4/, on the bolt h, between its nut '17 and the said segment, and by means of which thesegment may be raised or lowered. In order to still further secure the adjustment of the segment and prevent the same from being pulled out of position, the head-blocks G have vertical lugs'g, with perforations in their upper ends through which other adjusting-screws, i", are passed to bear against the rear edges of the segment-standards, as shown, and the segments are secured, when adjusted, by means of the nut '5" on the end of the bolt h, already described.

The carriage for supporting and handling the block will now be described. This is con- .structed chiefly of pipe or tubing, to enable one part to telescope or slide within another, as well as to insure great lightness of 0011- struction.

L L are the front and rear parts, formed of pipes whose ends are screwed into the hollow T-shaped elbows L L, and M M are the side parts, also screwed into the elbows L L.

N N are rods, which slide within the parts L L and support the carriage from the guides K K, which they grasp with their forked outer ends, and which have oil cups or openings n n on top, so that oil, 850., can be there admitted to lubricate the said guides, while the elbows L have set-screws Z to bear against the rods N, and secure all these parts rigidly together after they have been'adj usted to the required relative positions.

O is the left-hand dog-frame, having ends which hook over the rods L, and are rigidly secured thereto, after adjustment, by set-screws edged dog, 0, while 0 is the right-hand do frame, whose front end simply rests on the front rod L, without attachment thereto, and which is provided with a bottom plate, which extends under the rear rod L, while its operative face is divided into a series of teeth, 0 0, for the more ready attachment and detach ment of the block.

M is a loose sleeve on the rod M, and to this sleeve the standards at m are rigidly clamped, and between the plates of the forward standard is secured the shank of the handle M while the standards m m are connected to the dog-frame O by means of the links m m. The shank of the other handle, M, is simply secured by setscrew to the rod M.

The means for automatically tipping the table D D D will next be described. The rear end of the right-hand guide K is fitted with a collar, 70, against which a spring, K, bears, while between the other end of this spring and the forked ends of the rear rod N, and surrounding the guide K, is situated the sleeved end k of the short arm of a bent rod, K the forward end of which bears apawl, k, the operative end of which engages with-the notches p in the outer rim of a trefoil-cam, P. The said cam has ahollow grooved axle, l which is sustained within a cup-bearing, P bolted to the front end of the auxiliary frame A, the said cup-bearing having interior projections, 19, which fit within the groove 011 the exterior of the axle P, andthus sustain it. The free end of the lever F, already named, extends hooked plates q, with set-screws q 9 whereby,

the frame can be suspended on the front and rear carriage-rods L L and secured thereto, as shown. I

Q" Q areadditional longitudinal floor-beams, which are fastened rigidly to the angle-piece Q", and between which are located the bars R R, which carry the dogs for the spalts.

S S are transverse frames bolted to the under side of the angle end pieces, Q and with downward projections s s, carrying the dogbars R R, which latter are arranged in pairs,

as shown best in Fig. 8, so that the dogs r or r in each adjacent bar point in opposite directions. shaped) are provided with end extensions, R, which contain diagonal slots r extending in each bar in parallel direction with the dogs in said bar, and the said bars have also central vertical projections, R t, which are The said bars (which are angleprovided with perforations. the projections R and thesehave theholes 2" near their top w-hile'the bars lt have the prof ectionsi It, and these have theh olesanear their base. Theslotted endsR of these dQgbars extend between the downward projections 8 of the transverse frames S, and. are heldin place by the bolts 8, which pass th roughthe projections s and through the said slots o which slots aredisposed in opposite directions, as indicated by full and dotted lines in: Fig; 9. Each pair of dog-bars R i It is-connecte'd together in the centerbyineans' of the link '1, Fig. 10, which has bottom perforations, t, and above this, slot t, thehole It affording :means for bolt-connection with the-bar R through the hole r in its central projectiom-K, while theslot t affords similar. means ofibolt-connection with the bar B through the hole 2' in its central projection, R while near the top of each link '1 there is another: perforation, t

that connects with the horizontal links U, fcrmingpart of the actuating device of. the said dog-bars. V V are standardsbolted to the top of the beams Q?- near the frontends, and to thesestandards are pivoted the arms W XV of the handle agwhile near the said standards V the arms NV XV are perforated to receive the bolts a, that connect the front ends of the links U, whose other ends are connected by the bolts a to thelinksl,.asalready indicated.

X is the saw, supported horizontally at the rear of the machine on theupright shaft m, sustained, as shown, in suitable bearings; and Yis the pulley by which said shaftis actuated, and Z is theguard surrounding said saw.

The operation of our device is as follows: The parts being adjusted, say, as sh own in Fig. 2, with the tipping table inclined to theleft, the carriage is pulled forward by means of the handles M" M, the table is tilted to the right,

i and when the 'carriage'has been brought to the front of the machine over the table the handle M" is raised and the block is placed on the table,and then the ban dle M isdepressed, which action forces the teethof thedog Ofand the edge of the dog Ointothe block, as shown in Fig. 1, and then the operator pushes on the handles and forces the carriage, 101001;, &c., back against theacti on of the revolving saw, asshown in Fig. 3, which results in sawing off a shingle from thebottoni of the block, after which the carriage is again brought forward and the table tipped the other way, (which may be done by hand by the leveriEJso that the butt of the next shingle will lie to the left. Then the handle it is again raised, which withdraws the teeth from the block and permits thelatter t c-fall upon the inclined table, and then the handle M is again brought down, not only forcing the teeth of its dog into the block, but alsocrowding the block against the knife-edge o, as before, and, then the carriage and block are again pushed back, sawing off the shingle; and next the carriageis again brought forward, with the table tilted in the opposite The bars B have I direction, and this is repeated until the block is reduced to a spalt; but, in place of the hand-1e ver: E-,we prefer generally to use ourautomatic tipping device. Referring to Fig. 2, (wherein the table is supposed to be tipped to the left,)

i with this device, by the backward pressure of the-carriage, the-sleeve of the rearright-hand corner rod N presses against the sleeve k of the bent rod K and forces said rod back against the action of the spring K, and this causes the pawl k, which engages with one of the notches p in the outer rim of the cam P, to'also move back, turning the said cam back the distance between two notches, whereby as the cam begins to turn to the right the upperfriction roller 1 is forced downward until that point of the trefoil depressions which "was at the left of the said upper roller. is directly on top, and then, as the lower roller f is freed from the point whereon it rested, that roller drops into the hollow next thereto, and

automatically tipping the table again to the left. When the blocks have been sawed into shingles, there still remain portions of each block too thin to extend the distance between the dogs and the tipping table. and these portions are termed spaltsx Heretofore spalts have generally been waste products; but with our machine we are enabled to saw the entire spalt into shingles, and this we accomplish by means of our supplementary or spalt frame,

which issccured in the position shown in Fig.

4:,and then (the tipping table having been re moved, as it is not used) the carriage isdrawn forward, and the operator holds a spalt with one hand up against the under side of the timbers Q Q Q, and also against the inside edge of timber Q, (which extends down below the other timbers for this purpose,) while with the other hand he bears down upon the handle in,

and thereby forces the dogs 1" r into the spalt, and-which holds it securely, although the said dogs penetrate but a very slight distance, .in asmuch as they are forced into the spalt from opposite directions.

In order to saw the shingles from the spalt with the butts at alternate ends, the. guides K of the carriage must be alternately lower on IIO one side in the first notch of the segment and I spaltcarriage adapted, as described, to rethe corresponding pawl, H, on the other side of the machine in the second notch of the segment. Then, after the spalt has been pushed back against the saw, and one shingle sawed off, and the carriage drawn forward again, the pawl that was in the first notch is moved to the see ond notch and the spalt again pushed back, the two pawls being each in the second notch of their representative segments. The next adjustment is to advance the pawl that was originally in the second notch into the third notch, and the next adjustment (if the spalt requires so many) would be to bring the other pawl into the third notch of its segment, and thus the opposite pawls would be alternately moved a notch at a time as long as a chip remained of the spalt, and the guides K K would alternately be on a level with each other, and then the thickness of abutt apart in height, as stated.

In sawing from the block the thickness of the butt of each shingle is regulated in this manner:- When the leveling-bar B has been adjusted to position, screw-bolts b and b" are screwed up through the lugs B and B to the proper height, and there secured by their jamnuts, as shown in Fig. 1, so that as the support O of the tipping table oscillates from side to side the arms of the T-frame can. only drop the distance allowed by these bolts b and b, and hence the thickness of the butt is thereby determined, while the spring B and link 0* guard against accidental displacement; but in sawing from the spalt, as the tipping table and leveling-bar are not used, another method of adjustment becomes necessary, and we then regulate the thickness of the butt by raising or lowering the segments I by loosening the jam-nut i on the end of the bolt h, andthen turning the adjusting-screw i and then again tightening the nut 6 against the collar 11', the degree of elevationof the segment thus determining the thickness of the shingles as the teeth of the segment are brought nearer to or raised farther from the bolt h, which is the pivotal axle of the bell crank H; and to regulate the segments so as to enable the spaltframe to lower sufficiently to saw the last shingle held by the dogs r r, the adjustingscrews t' -are turned, which permits the required lateral adjustment of the segments I, and this is done, of course, before the jamnut i has been tightened to place.

In order to afford escape for the sawdust, the.1eft-hand side of our auxiliary frame is made open fromapoint beginning near the attachment of the saw-guard Z on that side, and extending forward nearly to the rear bracket, a, and as the saw rapidly revolves all the dust flies out at this point, leaving the work perfectly clear.
